A stable, strongly adherent oxide film protects titanium alloys from corrosion. This film forms instantly when a fresh surface is exposed to air or moisture. Anhydrous conditions in the absence of a source of oxygen should be avoided since the protective film may not be regenerated if damaged.

Titanium TI-6AL-4V-AMS-4911

Titanium is 30% stronger than steel, but is nearly 50% lighter. Titanium is 60% heavier than aluminum, but twice as strong. Titanium has excellent strength retention to 1,000 degrees Fahrenheit. Titanium is alloyed with aluminum, manganese, iron, molybdenum and other metals to increase strength, to withstand high temperatures, and to lighten the resultant alloy. Titanium’s high corrosion resistance is also a valuable characteristic; as when exposed to the atmosphere, titanium forms a tight, tenacious oxide film that resists many corrosive materials, particularly salt water.               

1) Have exceptionally high resistance to microbiologically induced corrosion (MIC)

2) Are highly resistant to oxidizing acids over a wide range of concentrations and temperatures. Common acids in this category include nitric, chromic, perchloric, and hypochlorous (wet Cl2) acids.
